Built in 1902, the much-photographed, 21-story Italian-Renaissance Flatiron Building (officially, the Fuller Building) was, despite local lore, neither the city's first skyscraper nor its first steel-skeleton building. Its wedge-shaped footprint—it's only 6.5 ft/2 m wide at its narrowest point—was designed to fit a triangular piece of land. The interior cannot be toured—it's now the home of publishing firms and offices—but there are a few cool shops there to make a stop worthwhile. No phone. 175 Fifth Ave. at 23rd Street (subway line F, N, R, V, W or 6 to 23rd Street), Manhattan, New York City.
